CALVIN LEVI RAINS, OF JOPLIN, MISSOURI.

COMBINED RIVET DOLLY AND HOLDER.

Application filed January 5, 1915. Serial No. see.

To all whom it may, concern Be it known that I, CALVIN LEVI RAINS, acitizen of the United States, residing at Joplin, in the county ofJasper and State of Missouri, have invented certain new and usefulImprovements in Combined Rivet Dollies and Holders; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to new and useful improvements in combined rivetdolly and holder, and my object is to provide a device to be heldagainst the headed end of a rivet, while the opposite end thereof isbeing upset.

A further object is to provide a magnet in unison with the dolly forholding the rivet while the first blows are delivered thereto in theupsettin operation. And a further object is to provide means forattaching the rivet holder or magnet to the dolly.

Qther objects and advantages will be here inafter set forth and moreparticularly pointed out in the accompanying specification.

In the accompanying drawings which are made a part of this application,Figure 1 is a perspective view of the device ready to be applied to use.Fig. 2 is a perspective view of the dolly with the rivet holding deviceremoved. Fig. 3 is a :)erspective View of the magnet or rivet holdingdevice, showing a Fig. l is a perspective view of the clamp employed insecuring the holder to the dolly, and Fig. 5 is a perspective view of ascrew employed for locking the clamp and holder in engagement with thedolly.

Referring to the drawings in which simi-.

lar' reference numerals designate correspon ding parts throughout theseveral views, 1 indicates the dolly or riveting bar, which is adaptedto be grasped by the hand and held in engagement with the headed end ofthe rivet while the opposite end thereof is being upset, the contactface 2 thereof being preferably flat to form a firm base for the head ofthe rivet, and if desired, the walls of the dolly adjacent the face 2,may be beveled or chamfered as shown at 3 so that the end of the dollymay be introduced into a narrow space.

A portion of the upper face of the dolly Specification of LettersPatent.

is cut away to form a flat base i and a shoulder 5 to receive the rivetholding device or magnet 6, the magnet resting edgewise on the base andhaving its rear end resting against the shoulder 5.

The magnet is formed preferably by bending a piece of flat metal insubstantially oval-shape, the free ends 7 thereof being extended in astraight line forwardly and parallel with each other, said ends 7 beingintroduced between the lugs 8 at the forward end of the base i, saidlugs holding the ends against spreading movement, at the same time beinga sufficient distance apart to allow the ends 7 to remain in spacedrelation.

The magnet is locked in position on the base by introducing a clamp 9over the upper edges of the parts of the magnet, said clamp havingchannels 10 to receive said edges, the clamp being locked in position byintroducing a screw or the like 11 through an opening 12 at the centerof the clamp and into a threaded aperture 13 in the dolly bar, thussecurely locking the magnet in position on the base portion of the bar.

In applying the magnet to use, a rivet 1% is placed against the forwardends of the end sections 7, and owing to the magnetic influence of themagnet, the rivet will be held in engagement therewith until it isintroduced through an opening and two or three blows given the free endof the rivet to partially upset the same, and in view of the fact that aslight upward pressure is directed against the end of the dolly bar, therebound from the blows delivered to partially upset the end of the rivetwill result in bouncing the end 2 of the dolly bar into engagement withthe head of the rivet, when the upsetting process can be completed andin view of the fact that the base of the magnet is seated against theshoulder 5, the initial blows to the rivet will not in any way affect orinjure the magnet.

This device can be used in the lighter riveting work and in view of itssimplicity can be readily and cheaply manufactured.

What I claim is 1. A dolly bar, comprising a bar, and a magnet upon aside of the bar, the active end of the magnet being substantially flushwith the end of the bar.

2. A dolly bar construction, comprising a dolly bar proper, having aseat formed near ment with the dolly bar.

In testimony whereof I have signed my name to tlns specifieatmn in thepresence of 1) two SUbECllblIlg wltnesses.
